If you use anything that's not a stock cam profile you will need a custom performance tune. Just keep that in mind as it can get expensive. I do happen to have a stock non AFM 5.3l profile btr ground aftermarket camshaft if you are interested. I'll sell it for less then btr does. I bought it off a guy who never used his kit. And sold the other parts. Well except the tuner that it came with. I should sell that too as I'll never use it. I need to verify it's unlocked first though I didn't really trust the guy I bought it from, didn't know him.
